also update the map SDK to the latest version

here's my code

 static const LatLng _center = const LatLng(45.521563, -122.677433);

  void _onMapCreated(GoogleMapController controller) {
    _controller.complete(controller);
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Maps Sample App'),
          backgroundColor: Colors.green[700],
        ),
        body: GoogleMap(
          onMapCreated: _onMapCreated,
          initialCameraPosition: CameraPosition(
            target: _center,
            zoom: 11.0,
          ),
        ),
      ),
    );
  }

Answer 1

I little improve on this solution, I am trying to use the webview plugin and I've faced the same error. I saw that my info.plist haven`t had the entry:

```
    <key>io.flutter.embedded_views_preview</key>
    <true/>
```

When I try to change the file directly in the androidstudio info.plist file, when hot reloading the file is reverted to the original value. After opening the ios project in the Xcode and using the GUI to change this entry, the error was solved.

I hope it can be useful for someone else.

Thanks

Try quit simulator then restart, flutter run again. I think -R hot restart doesn't reload Info.plist.

Answer 3

Just add this key value pair in info.plist file.

<key>io.flutter.embedded_views_preview</key>
<true/>
